Buzz

Buzz is an American English name derived as a pet form of Busby, though it has fully escaped that origin and operates as an independent word name evoking the sound of electricity, excitement, and high-frequency energy. It is most famously associated with Buzz Lightyear and astronaut Buzz Aldrin, the second man to walk on the moon.

Buzz is a name built for maximum energy. It is short, sharp, and buzzing with kinetic potential — the name of a dog who has never once been described as calm. The Toy Story connection (Buzz Lightyear, Space Ranger) gives it a beloved pop-culture warmth, while the astronaut Buzz Aldrin connection adds genuine heroic weight. Both versions of Buzz share a willingness to go further, higher, and faster than anyone around them. It suits high-drive working dogs, Jack Russell Terriers, and any pet whose idle speed is already faster than most animals' full effort. To infinity and beyond, indeed.
